The Job List is always limited by the Region dropdown, so be sure you have the correct region selected.
Also, beginning in v10 the Job List always has a maximum of 1000 jobs shown at one time. This is handled by the filter settings [View > Filter Options]. The ‘Show Maximum Jobs (Last Touched)’ filter is always added after other filters are applied. So to locate a job you may need to apply another filter such as date range.
